END PLATE FOR yRAIJW'AY BOX CARS.

Application alea :ranuary 11, 1924. serial 110.685,594.A` I' Theend'plates of railway box-cars andy tions, thereby allowing the roofframing tol become distorted, resulting in leaky roofs and damagedlading. i

This same weaving' and racking of the cars in service distorted the'sideframes or trusses of the cars, resulting in inoperative side doors andill-fitting side doors permittingV rain and sparks to ent-er the cai'. Y

This saine weaving and racking of the cars in service distorted the endiianiing of the cars contributing tothe cause of leaky roofs and causinginoperative and ill-.fitting end One of the objects of my invention isto provide a metallic end plate which can be used in the place of theusual wooden end plate having suflicient strength to perform itsfunction as a frame member and also to Another object of the inventionis to pro--V vide integral means in a metallic end plate to stiffen itto resist buckling and to transmit the stresses from the end posts aswell as the corner posts to the side wall of the car.

Another object of the invention is to provide means or method ofattaching suoli inetallio end plate to the side plates of the car,whereby a bracing effect is obtained between Lsuch frame members toretain the desired angularity between them. This, desiredresult isobtained'by attaching the end plate to both the inner and outer sides ofthe side plate. The end plate is then a. restrained beam whichis'considerably stronger than a loose en'd beam.

My improved end plate may be used tostrengthen and reinforce a woodenend y'vice applied thereon. y Y

plate already ina car or it may kbe'used as an end plateby'itself.

The metallic endplate may be used with a car. having an all metalreinforced end or it mayl be used with a car having a wooden endretaining wall and metallic frame members. y I

Another object of the inventioiiris to pro-y vide means of connecting ametallic end plate to both the inside and outside of the side wall of arailway box car.

In the drawings:

vfian'ge 6 conformingto the slopes ofthe root,

which flange is bent downwardly to form flange 7 which is secured toside plate 5 and corner post 3 by rivets 8 and also secured to sideplate 5 by rivets 9. In this manner the metallic end plate is secured toboth inside Yand outside of the side plate 5. The upper flange 6 forms agusset connection between the side plate 5y and portion l ofthe endplate,`thereby preserving the rectangularity vof the roof frame. Theportion l of the metallic end plate has considerable vertical 4depth atthe center of the vcar and is reinforced against bucklingv corrugatioii10 sotliat it has sufiicient strength as a frame member. The portion lalso has considerable -veitical'depth adjacent the corner post 8 so Ythat it?l forms a gusset and preserves the rectangularityofthe end frameof the car. TheV portion l is secured to the corner post by riv 7 is afragmentary side elevation of Fig. a plan View ofrrF ig. l. Y' Figl 1s afragmentary side elevation of `Rigid. i

ets'll. The flange 2 extends back on the side of the car av sufficientdistance to give it strength side plate which is part -of the sideframe.V

The'bottoni partof the corrugation 10 is horizontal and substantiallyparallel tothe lower edge of portion 1, while the upper part of thecorrugation 1() is preferably parallel to-the flanges 6. yThisarrangement gives a wider corrugation adjacent its longitudinal centerwhich is, therefore, stronger lat such point. The lower part of portion1 overlies the end post 17 and corner post 41 (see Figs.

9 and 5) so as to retain them in proper posi-y tion and prevent themfrom kicking out at the top. As shown in F ig. 9, the corrugation 10preferably overlies the upper ends of the corner postand end post. Thecorrugation terminates vadjacent the side plates. Any thrust, therefore,due to shifting lading, etc., is transmitted to the corrugation and bysaid corrugation to the side plates.

The end frame post 12 performs two functions: First, it' resists theimpacty of the lading throughV the lining boards 13 which im,

pact is transniitted to thcl metallic end plate by rivets 14 and 15. ltwill be noted that the end post 12 spans the corrugation' and thatrivets 14 and 15 are on opposite sides of the corrugation 10 which notonly efl'ectually carries the stress to the corrugation, but preventsthe corrugation from failing by opening up. Secondly, the end post is apart of the end frame Vand assists in resisting the stresses tending todistort the frame. On account of the great depth of portion l the rivets14 and 15 are spaced apart, giving 'a stronger,'connection than if theywere placed Connection angle 16 may be used to strengthen the connectionbetween the end post 12 and the portion 1.

Figs. 5. to 8 inclusive show the device as designed for application to acar having a' metallic end wall and a wooden side plate 31. Such a lcaris not usually provided with any end post, but otherwise the mechanicaladvantages claimed for the construction described herein aresubstantially the same.

The metallic end plate is providedV with the Avertical portion 32 whichhas the integral flange 33 extending along and secured to the sideframefof the car by bolts 34, 35i-and 36.'

The portion32 is provided with corrugation' The bottom edge of portion32 is offset at 38 to overlap the upper edge of metallic reinforce awooden end platewhichfis al? ready in the car. lt is an expensiveoperation to remove and replace one of these oldi wooden end plates; itis more economical to reinforce it by using a metallic end plate asdescribed herein.

The corrugation may bel formed to extend inwardly, as shown in 4, oroutwardly, as shown in Figs. 3 and 9, without deviating from the scopeof thisinvention. 1

ln the drawings the roof of the carvhas been eliminated for simplicity.l claim:

1; ln a railway boX car *having side plates,4

corner posts and end posts; a metallic end plate secured to said sidevplates and overlying said corner posts,s'aid end plate provided with anintegral coi'rugation, tlie'end post se'- cured to said end plate onboth sides of thel corrugation.

2. ln combination with the side plates of a railway box car, a metallicend plate having' a vertical portion and a portion conforming to theslopes of the roof, both portions secured to said side plates at theiropposite ends, said vertical portion having an integral corrngat-ionformed therein with itsl Yupper parts parallel tov the. slopes of theroof and withl its lower part'horizontah ln a railway car, thecombination of' side plates, a metallic end plate having an integralcorrugation formed vtherein extend# ing substantially to the oppositeside plates, said end plate p11-@vided with an integralj flangeconforming substantially tc the slopes of theroof, and end poststerminating adjacent said flange andV secured to said end plate on bothsides ofsaid corrugation.

4. in a. railway car, the 'combination Yof side plates, a'inetallic endplate having an integral corrugation lformed therein extend?" ingsubstantially to the opposite side plates, said end plate provided withan rintegral flange conforming substantially tothe' slopes of the roof,end posts terminating adjacent said flange and secured to said cndplatey on both sides of said corrugation, and cornerv posts terminatingadjacent said fiange.
